In this video, we'll use an EEPROM (28C16) to create a decimal display for an 8-bit value. The display uses multiplexing to drive four digits using a single EEPROM. As a bonus it supports both unsigned and signed (twos complement) display modes.

Parts list for the finished decimal display: - 1x 28C16 EEPROM - 1x 555 timer IC - 1x 74LS76 (Dual JK flip-flop) - 1x 74LS139 (Dual 2-line to 4-line decoder) - 4x Common cathode 7-segment displays - 1x 1k resistor - 1x 100k resistor - 2x 10nF capacitors
